PEA-HULLER.

SPECIFICATION forming part of Letters Patent No. 273,968, dated March 13, 1883.

Application filed December 29, 1882. (No model.)

To all whom it may concern: g l

Be it known thatI, WILLIAMT. GRUTGH- FIELD, of Henry Station, in the county of Henry and State of Tennessee', `have invented certain new and useful Improvements in'Pea- Hullers and I do hereby declare that the following is `a full, clear, and exact description'of theinvention,`which will enable others skilled in the art to which it appertains to `make and use the same, reference being had to the accompanying `drawings,whch form a part of this speciticatiomand in Which- I Figure lis a side viewof my improved peahuller. Fig. 2 is a similar view'from the other side. Fig. 3 is a longitudinal vertical section, and Fig. 4 is a cross-section,of the same; and Fig. 5 is a detail view of the si t'ter.

Similar letters of reference indicate corresponding parts 'in all the figures.

My invention has relation to pea-hullers 5` and it consists inthe improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

III the accompanying drawings, A represents the driver-shaft, which turns in bearings B upon the frame, and may be turned by hand, animal, steam, or any other power. Upon one end of the shaft is fastened a pnlley, (hand a wheel, D, overwhich passes a belt, E, which passes over a pulley, F, upon the cylinder-shaft G. e

H is the cylinder, which is covered by a e-hood, I, and to which thepeas-are fed through an opening, J, sliding down an inclined plate, K. The cylinder is provided with series of teeth, L, arranged spirally, `which pass be-A 4ing toward each perforation, seas-,to guide the `peas to4 the perforations, through which they pass, whilethe pods and straw are car-l ried off by the straw-carrier c. The separator is operated by. a crank-shaft, V, upon -Which a short pitman, W, is hinged, which is hinged to the end of the separator, and the separator slides upon strips or cleats, X, upon the sides ofthe frame, which it into grooves Y in the sides of the separator.

Immediately over the separator, at the point where the peas pass from the cylinder down upon the separator, is a hood, Z, having an apron, a, partly cutting off the opening from the cylinder, which prevents the thrashed peasfrom springing out at the opening for the passage of the straw. While the peas roll down the inclined 4bottom of the separator they are subjected to the blast from a fan,

t, which blows away the chaff and dust, after which they pass out under the machine, the

strawand pods being carried out of the ma- By the straw-carrier being reciprocated by the shaft d and` working over the reciprocating separator O the straw and` pods are Worked out at the rear of the machine, where they fall 4upon the ground, while the peas pass through the perforated top of the separator, guided by the grooves Uand prevented by themfrom being swept away by the straw.

Having thus described myinvention, I claim and desire to secure by Letters Patent of the i 9 2. The herein-described ,pea-huller,l consisting of the cylinder H, dat bridge N, hood Z, my own I have hereunto affixed my signature having apron a, reeiprocatin g separator 0, in presence of two Witnesses.
